Significance 4

Director John Bolduc purchases 15,380 shares at $6.49 across 2 transactions; stock down 33.2% from 52-week high.

John Bolduc, a director at WhiteHorse Finance, executed 2 separate purchases totaling 15,380 shares for $99,816.20 on 2026-06-18 at $6.49 per share, increasing his holdings by 5.2% to 313,890 shares. The purchase occurs in a deteriorating price environment: the stock is down 33.2% from its 52-week high of $9.66 and has declined 11.8% over the prior 30 days. Bolduc has recently accumulated shares across 5 transactions at WHF over a two-week window (2026-06-02 through 2026-06-18), though outcomes on these trades remain unmeasurable due to their recency. His broader cross-ticker track record shows limited predictive reliability, with 20 prior buys averaging a 0% win rate at the 90-day mark despite an initial 30-day average return of +6.4%, and a concerning 90-day average return of -6.8%. The company's fundamentals remain challenged, with a negative net income of -$687.0K, tempering the significance of this insider activity.

CEO Stuart Aronson bought 15,000 WHF shares at $6.41; stock down 34.2% from 52-week high.

Stuart D Aronson, Chief Executive Officer, purchased 15,000 shares at $6.41 on 2026-06-15, bringing his total holdings to 127,000 shares, a +13.4% increase in his position. The purchase occurs as the stock trades 34.2% below its 52-week high of $9.66, and the company reports net losses of $-687,000. Aronson has initiated five separate purchases at WHF within the prior three months (most recently on 2026-05-22), with measurable 30-day outcomes showing +8.1% and +6.6% gains on two earlier May-June purchases. His cross-ticker track record shows 66.67% 90-day win rate across 8 prior buys, though none of his same-ticker purchases have yet reached the 90-day measurement window, limiting the strength of inference about timing patterns at this specific holding.

Significance 4

Director John Bolduc bought 14,280 shares at blended $6.82 amid 2-insider cluster; stock down 12.4% in 30 days.

John Bolduc (Director) executed 4 separate purchases totaling 14,280 shares for $97,389.60, raising his holdings to 302,630 shares (+5.0% vs pre-transaction). The purchases were made at prices ranging from $6.76 to $6.88 on 2026-06-04 and 2026-06-05, with a blended average price of $6.82. This activity occurs within a cluster pattern: 2 other insiders also bought within the past 14 days at WHF. However, context suggests caution—the stock is currently trading at $6.66 (below his average purchase price), down 12.4% over the past 30 days and 31.1% from its 52-week high of $9.66. His prior trades at WHF show mixed timing, with only 1 of 5 prior buys well-timed at the 90-day mark, and recent purchases on 2026-06-02 and 2026-06-01 tracking nearly flat to slightly negative. Additionally, the company reported net income of $-687,000.00.

Significance 5

Director Bolduc (WHF) buys 14,280 shares at $6.81–$6.88; stock down 30.0% from 52-week high as cluster buy emerges

John Bolduc, Director at WhiteHorse Finance, made 4 separate purchases totaling 14,280 shares for $97,746.60 on 2026-06-01 and 2026-06-02 at prices ranging from $6.81 to $6.88. This transaction lifted his holdings to 295,490 shares, a 5.1% increase from pre-transaction levels. The current stock price of $6.76 sits 30.0% below the 52-week high and has declined 10.9% over the past 30 days, creating a backdrop of recent weakness. Notably, 3 other insiders also purchased WHF shares within the past 14 days, forming a cluster buy pattern. Historically, Bolduc's 5 prior trades at WHF have shown no instances of favorable 90-day outcomes—all prior buys were followed by declines. His cross-ticker track record across 20 open-market buys shows a 20.00% 90-day win rate with an average 90-day return of -4.0%, indicating a pattern of poor long-term timing on equity purchases.

Director John Bolduc buys 21,420 shares at WHF for $146,191.50 in 6 transactions; stock down 11.6% in 30 days

John Bolduc purchased 21,420 shares for $146,191.50 across 6 separate transactions between 2026-05-27 and 2026-05-29, at prices ranging from $6.76 to $6.91, increasing his holdings by 8.1% to 284,780 shares. The current price of $6.69 sits 30.8% below the 52-week high of $9.66, with a 30-day change of -11.6%, placing the stock in a downtrend. His 5 prior trades at WHF all showed negative 90-day returns (-5.9% to -6.2%), establishing a pattern where purchases have not preceded price recovery at this ticker. A cluster of 2 other insiders also buying within the past 14 days is noted alongside this filing, though no earnings or fundamental trigger is evident given net income of $-687,000.00.

Significance 4

CFO Joyson Thomas buys 3,000 WHF shares at $6.62; holdings rise to 25,000 shares post-transaction.

Joyson Thomas, the CFO, purchased 3,000 shares at $6.62, increasing his stake from 22,000 to 25,000 shares—a 13.6% increase in holdings. The timing occurs after a significant pullback: the stock is -31.5% from its 52-week high of $9.66 and down -12.0% over the past 30 days, though it has recovered 4.1% over the past 90 days. His cross-ticker track record shows 1 prior buy with a 100% 90-day win rate and his prior WHF purchase on 2025-12-24 was followed by a positive 90-day return. However, the company's fundamentals show a net loss of -$687,000.00, which creates a structural headwind against accumulation being a clear conviction signal. The modest dollar value of $19,860.00 relative to his growing position suggests maintenance or modest reallocation rather than aggressive conviction in depressed valuations.

CEO Aronson buys 32,000 shares ($210.1K) at WHF; holdings rise to 100.0K (+47.1% vs prior)

Stuart D Aronson, CEO of WhiteHorse Finance, executed 3 separate purchases totaling 32,000 shares for $210,060.00 at a blended average price of $6.56, raising his post-transaction holdings to 100,000 shares. The current stock price of $6.62 is -31.5% from the 52-week high of $9.66, and the stock has declined -12.0% over the past 30 days. Among Aronson's prior trades at WHF, 2 of 5 prior buys were well-timed at the 90-day mark, suggesting mixed execution timing at this ticker. The company reported net income of -$687,000.00, indicating ongoing operational losses despite the insider's continued accumulation.

Significance 6

CEO Aronson bought 13,000 shares at blended $7.01; holding rises 22% to 72,000. Two other insiders bought in 14-day cluster.

Aronson Stuart D, CEO of WhiteHorse Finance, executed 2 separate purchases totaling 13,000 shares for $91,100.00, increasing his holdings by 22.0% from 59,000 shares to 72,000 shares. The purchases occurred at $6.95 and $7.10—prices near the current price of $7.05 but well below the 52-week high of $10.34. At the same-ticker level, Aronson's prior 3 buys at WHF were timed favorably, with 2 of 3 showing positive 90-day returns, suggesting selective buying discipline. The clustering of purchases among 2 other insiders within 14 days indicates coordinated interest in the stock at current levels, though the company reports negative net income of $-556,000.00. The absence of a scheduled trading plan (10b5-1) in the filing suggests these were discretionary purchases at a depressed price relative to 52-week range, warranting investor assessment of underlying business conditions.

Significance 3

Director John Paul Volpe purchases 1.0K shares of WhF at $7.18, initiating position despite company's -$556.0K net loss

John Paul Volpe, a director of WhiteHorse Finance, made an initial purchase of 1,000 shares at $7.18 on March 13, 2026, establishing a new position after holding zero shares. The current price of $7.31 reflects only modest appreciation since the transaction, with the stock down -29.3% from its 52-week high of $10.34. Volpe's prior buy at this same ticker on November 12, 2025 showed limited success, delivering -6.0% return over 90 days, which represents a pattern of unsuccessful timing at WHF. The company reports a net loss of -$556.0K, adding context to the modest transaction size and suggesting the insider is entering a challenged business environment rather than reacting to a turnaround signal.

Significance 4

Director Bolduc buys 25,170 shares in 6 transactions at blended avg $7.14; current price $7.07, -31.6% from 52-week high.

Director John Bolduc executed 6 separate open-market purchases totaling 25,170 shares for $179,587.95 at a blended average price of $7.14 per share between March 12–16, 2026, increasing his holdings by 10.2% to 272,820 shares. The purchases occurred as WhiteHorse Finance trades at $7.07, down -31.6% from its 52-week high of $10.34, though the stock has appreciated +7.9% over the prior 30 days. The company's fundamentals show negative net income of $-556,000.00 and a P/E of 11.78; Bolduc's cross-ticker track record shows modest historical accuracy (90-day win rate 33.33% across 20 prior buys), and his prior four same-ticker buys at WHF earlier in March remain too recent to measure outcomes. The accumulation pattern—six transactions in four days at a relatively depressed price level—warrants observation, though the absence of documented prior well-timed exits at this ticker and the company's current operating loss limit strong conviction-derived interpretation.
